Marco Antonio de Mattos Filho (born 3 July 1986 in Passo Fundo), commonly known as Marquinho, is a Brazilian footballer who plays for Fluminense. Mainly an attacking midfielder, he can also play as a left wingback.
Marquinho started in football at Gaúcho, playing for other Rio Grande do Sul-based youth clubs until he was transferred to Vasco da Gama and later to Palmeiras. During his time at Palmeiras, he was promoted to the first team in 2007 after his manager threatened not to renew Marquinho's contract since he acted only in Palmeiras B without first team opportunities.
His first game in the first team was on January 18, 2007 in a 4–2 win at Campeonato Paulista. He also played at Brasileirão against Goiás in August 2007 before moving to Botafogo. In 2008, after being discharged from the Rio de Janeiro club, he was signed by Figueirense, being a member of the starting eleven and moving to Fluminense the following year. At the end of 2009, after a long battle against relegation, Marquinho scored in the 1-1 away draw against Coritiba in the last league match, a result that kept Fluminense at Série A and relegated Coritiba to Série B. In 2010, he was part of the team that led Fluminense to win the national title after 26 years.
Marquinho moved to Roma on 31 January 2012 on a six-month loan. He made his debut on 19 February against Parma and scored his first goal on 1 April in a 5–2 win against Novara. He scored a goal against Udinese on 11 April 2012, and one more against Napoli two weeks later. At the end of a very impressive spell at Roma, they officially signed the midfielder for a reportedly €3 million from Fluminense.
He scored his first goal of the season against Inter on 2 September 2012 in a 3–1 victory. He scored his second goal of the season in a 4–2 loss against Cagliari. He finished the season with 26 appearances and 4 goals.
On 2 July 2014, the Jeddah-based team Ittihad FC announced the signing of Marquinho on a season long loan from A.S. Roma for undisclosed fee. He performs very well with Ittihad FC and scored 8 goals in 14 league matches. On May 15, 2015 following the derby match against Al-Ahli, Marquinho left Saudi Arabia.
On 14 July 2016, Marquinho joined Fluminense on a three-year contract.
